Quantitative measurement of human chorionic gonadotropin (hCG) based on digital image processing

摘要

Our research aims to develop a novel method for quantitative measurement of hCG concentration in human serum. Based on digital imaging processing technique, the relationship between hCG concentration and image information of reaction dot on hCG test sample can be built and be described as a standard curve. According to this standard curve, concentration of hCG sample can be measured. The image information of hCG test sample is captured by CCD mini-camera and is processed by digital signal processor (DSP). The sensitivity can be under 10mIU/ml. The high accuracy makes our system significantly potential application in clinical diagnosis.
